Microsoft has started selling three fingerprint readers from BIO-Key that support the Windows Hello security features in Windows 10 PCs. The devices are available at Microsoft's retail stores and on its website for $39.99 each.

The three products include the BIO-key SideSwipe Mini Fingerprint Reader and the SideTouch Fingerprint Reader, both of which connect directly to a Windows 10 PC or tablet. There's also the EcoID Fingerprint Reader, which uses a USB cord to connect the PC to the reader. Microsoft states:

These devices enable you to login conveniently and securely to your Windows 10 PC with a simple swipe or touch. With Windows Hello you can sign into your Windows devices in less than 2 seconds – that's 3 times faster than a password that you have to remember and type in; also, with Windows Hello and the Anniversary Update, you can now sign into compatible apps and Microsoft Edge websites.

Why would you even use this on a Surface Pro given it can do Windows Hello auth via camera? Their both biometric forms of auth. The only situation I can think of is in businesses where cameras are banned..

Definitely a much more affordable option than the fingerprint reader Surface keyboards, and you can use it without the keyboard attach. Although I wish it has a nicer design, or some other colours like silver to match the Surface at least.

I saw the SideTouch attached to a laptop last night at the Microsoft Store. I thought it came with the laptop and didn't realise they were being sold on their own. Nice to know if I'm ever in the market for a biometric device.

Do some of these models work without "swiping" your finger? I've got one of the cheap fingerprint readers that you need to swipe your finger on, but I'm not happy with the accuracy (it was dirt cheap though) so I'd like something that works like the readers on mobile phones, that you just touch.
